Cobblestone Lichen
''Acarospora'' is a genus of mostly lichen-forming fungi in the family Acarosporaceae. Most species in the genus are crustose lichens that grow on rocks in open and arid places all over the world. They may look like a cobblestone road or cracked up old paint, and are commonly called cobblestone lichens or cracked lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, They usually grow on rock (are " saxicolous"), but some grow on soil (terricolous) or on other lichens. Some species in the genus are fungi that live as parasites on other lichens (lichenicolous fungi). ''Acarospora'' is a widely distributed genus, with about 128 species according to a 2008 estimate. Species in ''Acarospora'' may be shiny as if covered with a glossy varnish, or dull and powdery looking. They have a diverse range of colors, from the brilliant yellow bright cobblestone lichen, to the dark reddish-brown mountain cobblestone lichen, or they can appear tan, gray, ...

Mountain Cobblestone Lichen
''Acarospora elevata'', the mountain cobblestone lichen, is a shiny dark reddish brown to dark brown verrucose to aereolate crustose lichen that grows up to wide on granite in central and southern California to Baja California, and high elevations in the Rocky Mountains.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichen Flora of the Greater Sonoran Desert Region. Vol 3., Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001/ref> It is usually only found above because it is eaten by red mites at lower elevations. In the Californias, it is mostly found at high elevations (hence ''"elevata"''), but sometimes in coastal locations where it is less glossy. It grows in full sun, mostly on hard granite, but sometimes other igneous or carbonate rock, from in elevation. It may start by growing on members of the genus ''Aspicilia'', or other such pioneer species on hard rocks. There are typically between zero and four apothecia on each ar ...

Stipes
Crucifixion is a method of capital punishment in which the victim is tied or nailed to a large wooden cross or beam and left to hang until eventual death from exhaustion and asphyxiation. It was used as a punishment by the Persians, Carthaginians and Romans, among others. Crucifixion has been used in parts of the world as recently as the twentieth century. The crucifixion of Jesus of Nazareth is central to Christianity, and the cross (sometimes depicting Jesus nailed to it) is the main religious symbol for many Christian churches. Terminology Ancient Greek has two verbs for crucify: (), from (which in today's Greek only means "cross" but which in antiquity was used of any kind of wooden pole, pointed or blunt, bare or with attachments) and () "crucify on a plank", together with ( "impale"). In earlier pre-Roman Greek texts usually means "impale". The Greek used in the Christian New Testament uses four verbs, three of them based upon (), usually translated "cross". T ...

Squamulose
A squamulose lichen is a lichen that is composed of small, often overlapping "scales" called squamules. If they are raised from the substrate and appear leafy, the lichen may appear to be a foliose lichen, but the underside does not have a "skin" (cortex), as foliose lichens do. Squamulose lichens are composed of flattish units that are usually tightly clustered. They are like an intermediate between crustose and foliose lichens. Examples of squamulose lichen include ''Vahliella leucophaea'', ''Cladonia subcervicornis'' and ''Lichenomphalia hudsoniana ''Lichenomphalia hudsoniana'' is a species of basidiolichen in the family Hygrophoraceae. It is widely distributed in alpine and arctic regions of the world, where it grows on moist soil amongst moss. Taxonomy The species was first species descr ...''.

Areoles
In botany, areoles are small light- to dark-colored bumps on cactus, cacti out of which grow clusters of Thorns, spines, and prickles, spines. Areoles are important diagnostic features of cactus, cacti, and identify them as a family distinct from other succulent plants. Gordon Douglas Rowley, Gordon Rowley - What is an Areole The spines are not easily detachable, but on certain cacti, members of the subfamily Opuntioideae, smaller, detachable bristles, glochids, also grow out of the areoles and afford additional protection. Areoles represent highly specialized branches on cacti. Apparently, they evolved as abortive branch buds while their spines evolved as vestigial leaves. In branched cacti, such as Opuntioidiae and the saguaro, new branches grow from areoles, because that is where the buds are. The development of the areole seems to have been an important element in the adaptation of cacti to niches in desert ecology. Some of the Opuntioideae have spines, as well as glochids ...

Dried Lake
Drying is a mass transfer process consisting of the removal of water or another solvent by evaporation from a solid, semi-solid or liquid. This process is often used as a final production step before selling or packaging products. To be considered "dried", the final product must be solid, in the form of a continuous sheet (e.g., paper), long pieces (e.g., wood), particles (e.g., cereal grains or corn flakes) or powder (e.g., sand, salt, washing powder, milk powder). A source of heat and an agent to remove the vapor produced by the process are often involved. In bioproducts like food, grains, and pharmaceuticals like vaccines, the solvent to be removed is almost invariably water. Desiccation may be synonymous with drying or considered an extreme form of drying. In the most common case, a gas stream, e.g., air, applies the heat by convection and carries away the vapor as humidity. Other possibilities are vacuum drying, where heat is supplied by conduction or radiation (or microwav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squamulous
A squamulose lichen is a lichen that is composed of small, often overlapping "scales" called squamules. If they are raised from the substrate and appear leafy, the lichen may appear to be a foliose lichen, but the underside does not have a "skin" ( cortex), as foliose lichens do. Squamulose lichens are composed of flattish units that are usually tightly clustered. They are like an intermediate between crustose and foliose lichens. Examples of squamulose lichen include ''Vahliella leucophaea'', ''Cladonia subcervicornis'' and ''Lichenomphalia hudsoniana ''Lichenomphalia hudsoniana'' is a species of basidiolichen in the family Hygrophoraceae.

Areolate
Lichens are composite organisms made up of multiple species: a fungal partner, one or more photosynthetic partners, and sometimes a basidiomycete yeast. They are regularly grouped by their external appearance – a characteristic known as their growth form. Lichenologists have described a dozen of these forms: areolate, byssoid, calicioid, cladoniform, crustose, filamentous, foliose, fruticose, gelatinous, leprose, placoidioid and squamulose. Of these, crustose, foliose and fruticose are the most commonly encountered. With the exception of calicioid lichens, growth forms are based on the appearance of the thallus, which is the vegetative (non-reproductive) part of the lichen. In most species, this form is determined by the lichen's fungal partner, though in a small number, it is instead the photobiont that determines the lichen's morphology. In some growth forms, the outermost layer of the thallus consists of tightly woven fungal . This layer, known as the cortex, may be found ...

Dry Lake Bed
A dry lake bed, also known as a playa, is a basin or depression that formerly contained a standing surface water body, which disappears when evaporation processes exceeds recharge. If the floor of a dry lake is covered by deposits of alkaline compounds, it is known as an alkali flat. If covered with salt, it is known as a '' salt flat.'' Terminology If its basin is primarily salt, then a dry lake bed is called a '' salt pan'', ''pan'', or ''salt flat'' (the latter being a remnant of a salt lake). ''Hardpan'' is the dry terminus of an internally drained basin in a dry climate, a designation typically used in the Great Basin of the western United States. Another term for dry lake bed is ''playa''. The Spanish word ''playa'' () literally means "beach". Dry lakes are known by this name in some parts of Mexico and the western United States. This term is used e.g. on the Llano Estacado and other parts of the Southern High Plains and is commonly used to address paleolake sediments ...
